What it is
[Contains CMC-like ingredients to regulate moisture and straighten hair from the inside!] Dryness and frizz are caused by an imbalance in the moisture balance within hair. Focusing on the function of CMC, which bonds the cuticle covering the surface, this product locks in moisture stored within. [Moisture-charged! Rich in wool keratin] Formulated with wool keratin, the same main component of hair, as a moisturizing ingredient. Strengthens frizzy and damaged hair, giving it beautiful bounce and shine. [Heat-protecting effect thoroughly cares for damaged hair from the inside!] Contains erucalactone, a plant-derived ingredient with the ability to bond with hair when exposed to heat. Repairs damage while protecting hair from the heat of hair dryers and hair irons.

We're working on rolling out prepaid duties for more countries soon.
